Why is the car’s air conditioning oil important?

The car's air conditioning oil is important because it lubricates the air conditioning system's compressor, which is the main component that makes the cooling system work. Without a sufficient amount of oil, the compressor can suffer damage and eventually fail, which would result in a costly repair. The oil also helps to seal the air conditioning system and prevent coolant leaks. In summary, maintaining the appropriate oil level in the car's air conditioning system is crucial for the proper functioning of the system and to prevent costly repairs in the future.
